When an element is not grabbed (the value is set to false or undefined, or the attribute is removed), authors SHOULD revert the aria-dropeffect attributes of the associated drop targets to none. Programmatic access to accessibility semantics is essential for assistive technologies. Advisory information about roles that inherit the state or property from an ancestor role.

Roles are applied by placing their names among the tokens appearing in the value of a host-language-provided role attribute.

It clarifies semantics to assistive technologies when authors create new types of objects, via style and script, that are not yet directly supported by the language of the page, because the invention of new types of objects is faster than standardized support for them appears in web languages. An author MAY choose to propagate selection in this manner depending on the specific application. When the ARIA attribute definition includes a table listing the attribute's allowed values, WAI-ARIA should only be used in cases where the host language lacks the needed role, state, and property indicators.
